Les figures 1a et 1b représentent une porte d'écluse roulante 1 selon l'invention. Ladite porte comprend une structure rigide de forme générale parallélépipédique, et présente une première face principale 11 et une deuxième face principale 12, ces deux faces principales 11,12 étant opposées et sensiblement parallèles entre elles. De plus, la porte d'écluse roulante 1 selon l'invention comprend une face supérieure 15, une face inférieure 10, une face d'extrémité avant 13 et une face d'extrémité arrière 14. Lesdites faces inférieure 10, principales 11,12, d'extrémité avant 13, d'extrémité arrière 14, et supérieure 15 délimitent ensemble un espace intérieur de porte 16. Compte tenu des efforts importants auxquels est soumise la porte d'écluse, cet espace intérieur de porte 16 est notamment muni de préférence de multiples armatures et renforts 18 disposés en treillis, comme cela est illustré dans la figure 1b.The figures 1a and 1b represent a rolling lock gate 1 according to the invention. Said door comprises a rigid structure of parallelepipedal general shape, and has a first main face 11 and a second main face 12, these two main faces 11,12 being opposite and substantially parallel to each other. In addition, the rolling lock gate 1 according to the invention comprises an upper face 15, a lower face 10, a front end face 13 and a rear end face 14. Said lower faces 10, main 11.12 , front end 13, rear end 14, and upper 15 together define an interior door space 16. Given the significant forces to which the lock gate is subjected, this interior door space 16 is preferably provided with multiple reinforcements and reinforcements 18 arranged in lattice, as illustrated in FIG. figure 1b .

Sur toutes les figures sur lesquels ils sont représentés, les axes du repère cartésien sont définis comme suit : l'axe Z est vertical et orienté vers le haut, l'axe Y est parallèle à la plus grande dimension (longueur) de la porte, et l'axe X est perpendiculaire aux deux faces principales 11,12.In all the figures on which they are represented, the axes of the Cartesian coordinate system are defined as follows: the Z axis is vertical and oriented upwards, the Y axis is parallel to the largest dimension (length) of the door, and the X axis is perpendicular to the two main faces 11,12.

De plus, la porte d'écluse roulante 1 selon l'invention contient dans sa partie inférieure une cavité d'accès 3, ouverte vers le bas. Cette cavité d'accès peut de préférence, comme représenté sur la figure 1b, s'étendre sur une majeure partie de la longueur de la face inférieure, prenant ainsi la forme générale d'un tunnel, nonobstant la présence de renforts inférieurs 18.In addition, the rolling lock gate 1 according to the invention contains in its lower part an access cavity 3, open downwards. This access cavity may preferably, as shown in FIG. figure 1b extend over a greater part of the length of the lower face, thus taking the general shape of a tunnel, notwithstanding the presence of lower reinforcements 18.

La porte d'écluse roulante 1 selon l'invention contient également un premier dispositif d'étanchéité 31,32,33 ayant une forme générale de 'U' ouvert vers le haut, situé le long des bords de la première face principale 11, ayant une portion inférieure horizontale 31, une portion verticale avant 33 et une portion verticale arrière 32. Le cas échéant, la porte d'écluse roulante 1 selon l'invention peut aussi contenir un deuxième dispositif d'étanchéité 34,35,36, ayant également une forme générale de 'U' ouvert vers le haut, situé le long des bords de la deuxième face principale 12, ayant une portion inférieure horizontale 34, une portion verticale avant 36 et une portion verticale arrière 35.The rolling lock gate 1 according to the invention also contains a first sealing device 31, 32, 33 having a generally U-shaped shape open upwards, situated along the edges of the first main face 11, having a horizontal bottom portion 31, a front vertical portion 33 and a vertical portion rear 32. Where appropriate, the rolling lock gate 1 according to the invention may also contain a second sealing device 34,35,36, also having a general shape of 'U' open upwards, located along edges of the second main face 12, having a horizontal lower portion 34, a front vertical portion 36 and a rearward vertical portion 35.

Ces premier et deuxième dispositifs d'étanchéité 31 à 36 sont réalisés de préférence, mais non exclusivement en bois, et présentent une section par exemple rectangulaire.These first and second sealing devices 31 to 36 are preferably, but not exclusively made of wood, and have a rectangular section for example.

En outre, la porte d'écluse roulante 1 selon l'invention peut aussi contenir un joint d'étanchéité gonflable 6, ayant lui aussi une forme générale de 'U' ouvert vers le haut, situé sur les bords de la première face principale 11. Le joint d'étanchéité gonflable 6 est adjacent au premier dispositif d'étanchéité 31,32,33 sur toute la longueur de celui-ci, et ses dimensions selon les axes Y et Z sont légèrement inférieures aux dimensions du premier dispositif d'étanchéité 31,32,33 selon les axes Y et Z, de sorte que le 'U' que parcourt le joint d'étanchéité gonflable s'inscrit juste à l'intérieur du 'U' que parcourt le premier dispositif d'étanchéité 31,32,33.In addition, the rolling lock gate 1 according to the invention may also contain an inflatable seal 6, also having an overall shape of 'U' open upwards, located on the edges of the first main face 11 The inflatable seal 6 is adjacent to the first seal 31,32,33 throughout the length thereof, and its dimensions along the Y and Z axes are slightly smaller than the dimensions of the first seal 31,32,33 along the Y and Z axes, so that the 'U' traveled by the inflatable seal fits just inside the 'U' that runs through the first seal 31,32 33.

Le joint d'étanchéité gonflable 6 comporte une portion rigide fixé à la première face principale, et une portion flexible, réalisée par exemple à base de caoutchouc ou de plastique souple.The inflatable seal 6 comprises a rigid portion fixed to the first main face, and a flexible portion, made for example based on rubber or flexible plastic.

Tous ces dispositifs d'étanchéité, et notamment leur fonctionnement, seront décrits en détails plus loin dans la présente description.All these sealing devices, and in particular their operation, will be described in detail later in the present description.

La porte d'écluse roulante 1 selon l'invention se déplace en roulant selon l'axe Y grâce à deux dispositifs de roulement, un dispositif de roulement inférieur 4 et un dispositif de roulement supérieur 5. Le dispositif de roulement inférieur 4 est muni d'au moins une première roue 42 roulant sur au moins un rail inférieur 41 et le dispositif de roulement supérieur 5 est muni d'au moins une deuxième roue 52 roulant sur au moins un rail supérieur 51.The rolling lock gate 1 according to the invention moves by rolling along the Y axis by means of two rolling devices, a lower rolling device 4 and an upper rolling device 5. The lower rolling device 4 is provided with at least one first wheel 42 rolling on at least one lower rail 41 and the upper rolling device 5 is provided with at least one second wheel 52 rolling on at least one upper rail 51.

Les figures 2a, 2b et 2c illustrent schématiquement certaines configurations d'une écluse comprenant une porte d'écluse roulante 1 selon l'invention, notamment en relation avec un premier espace 81 qui peut être rempli de liquide et avec un deuxième espace 82 qui peut lui aussi être rempli de liquide, le liquide en question étant généralement de l'eau, par exemple de l'eau de mer ou de l'eau douce. Dans la configuration représentée à titre d'exemple non limitatif dans les figures 2a à 2c, le premier espace 81 est une étendue d'eau soumise à un niveau variable, en l'occurrence cela peut être la mer ou l'océan, et le deuxième espace 82 est une étendue d'eau ayant certaines limites, comme un bassin ou un sas.The Figures 2a, 2b and 2c schematically illustrate certain configurations of a lock comprising a rolling lock gate 1 according to the invention, in particular in relation to a first space 81 which can be filled with liquid and with a second space 82 which can also be filled with liquid, the liquid in question being generally water, for example seawater or fresh water. In the configuration shown by way of non-limiting example in the Figures 2a to 2c , the first space 81 is a stretch of water subject to a variable level, in this case it may be the sea or the ocean, and the second space 82 is a stretch of water having certain limits, such as a pool or an airlock.

Dans la figure 2a, la porte d'écluse roulante 1 est située dans son logement de retrait 7, et les deux espaces de liquides 81 et 82 sont en communication directe, offrant ainsi un passage libre pour les navires qui peuvent passer du premier espace 81 au deuxième espace 82, ou inversement du deuxième au premier espace. Dans cette configuration la porte d'écluse est dans une position qu'on dénomme 'ouverte'.In the figure 2a , the rolling lock gate 1 is located in its withdrawal housing 7, and the two liquid spaces 81 and 82 are in direct communication, thus providing a free passage for ships that can pass from the first space 81 to the second space 82 , or conversely from the second to the first space. In this configuration the lock gate is in a position called 'open'.

Par opposition, dans les figures 2b et 2c, la porte d'écluse est dans une position qu'on dénomme 'fermée' dans laquelle elle sépare les deux espaces liquides 81,82 l'un de l'autre. Dans la figure 2b, le premier espace de liquide 81 est soumis à un niveau variable, et n'est plus en communication liquide avec le deuxième espace de liquide 82 qui, lui, est soumis à un niveau maîtrisé. Le niveau de ce deuxième espace de liquide 82 peut être maintenu constant dans le cas d'un bassin à flot, ou bien encore abaissé ou relevé dans le cas d'un sas entre deux biefs selon le souhait des utilisateurs de l'écluse. Les moyens pour contrôler le niveau du deuxième espace de liquide 82 étant connu dans l'art, ils ne seront pas décrits en détails.In contrast, in Figures 2b and 2c , the sluice gate is in a position called 'closed' in which it separates the two liquid spaces 81,82 from one another. In the figure 2b , the first liquid space 81 is subjected to a variable level, and is no longer in liquid communication with the second liquid space 82 which itself is subjected to a controlled level. The level of this second liquid space 82 can be kept constant in the case of a pond afloat, or even lowered or raised in the case of an airlock between two reaches as desired by the users of the lock. Since the means for controlling the level of the second liquid space 82 are known in the art, they will not be described in detail.

La figure 2c montre une utilisation particulière d'une porte d'écluse selon l'invention. En effet, dans ce cas, le deuxième espace de liquide 82 est vidé de son liquide et accueille un chantier de construction ou de réparation de navire. Le deuxième espace ainsi asséché permet de construire ou de réparer un navire, opération qui peut durer un temps important comme plusieurs mois ou années. A l'issue de l'opération de construction ou de réparation, le navire est remis à l'eau très simplement en laissant de l'eau pénétrer dans le deuxième espace 82 puis, lorsque le niveau de liquide du deuxième espace 82 a rejoint le niveau du premier espace 81, on procède à l'ouverture de la porte d'écluse par déplacement vers son logement de retrait 7, et le navire peut ainsi rejoindre le premier espace 81, c'est-à-dire prendre la mer.The Figure 2c shows a particular use of a lock gate according to the invention. Indeed, in this case, the second liquid space 82 is emptied of its liquid and hosts a construction site or ship repair. The second space thus dried makes it possible to build or to repair a ship, operation which can last a significant time like several months or years. At the end of the construction or repair operation, the ship is simply returned to the water by allowing water to enter the second space 82 and then, when the liquid level of the second space 82 has reached the first space 81 level, it proceeds to the opening of the lock gate by moving to its recess housing 7, and the ship can thus join the first space 81, that is to say, to go to sea.

Les figures 4a et 4b présentent respectivement chacune une coupe de la maçonnerie d'écluse seule, avant l'installation de la porte d'écluse. Le logement de retrait 7 de la porte comporte une première paroi 71, un fond 72 et une seconde paroi 73. Par ailleurs, la maçonnerie de l'écluse comprend une première portée 61,62,63 comprenant une portion inférieure 61, une portion verticale avant 63 et une portion verticale arrière 62. De même, la maçonnerie de l'écluse comprend le cas échéant une deuxième portée 64,65,66 comprenant une portion inférieure 64, une portion verticale avant 66 et une portion verticale arrière 65. En outre, la maçonnerie de l'écluse peut comprendre une portée auxiliaire 67,68,69 comprenant une portion horizontale 67, une portion verticale avant 69 et une portion verticale arrière 68.The Figures 4a and 4b respectively present a section of the lock masonry alone, prior to the installation of the lock gate. The recess housing 7 of the door has a first wall 71, a bottom 72 and a second wall 73. Furthermore, the masonry of the lock comprises a first span 61,62,63 comprising a lower portion 61, a vertical portion before 63 and a rear vertical portion 62. Likewise, the masonry of the lock comprises, where appropriate, a second span 64, 65, 66 comprising a lower portion 64, a vertical portion before 66 and a rear vertical portion 65. , the masonry of the lock may include an auxiliary bearing 67,68,69 including a horizontal portion 67, a front vertical portion 69 and a rear vertical portion 68.

Par ailleurs la maçonnerie comprend un chemin de roulement 2, situé entre lesdites portions inférieures 61,64 desdites première et deuxième portées appartenant à la maçonnerie, pour recevoir au moins un rail 41 sur lequel roule le dispositif de roulement inférieur 4 de la porte d'écluse. Ce chemin de roulement 2 comprend de préférence au moins un autre rail 41, et le dispositif de roulement inférieur 4 comprend au moins une roue 42, de manière préférée deux roues 42 ou bien encore quatre roues 42 comme représenté sur la figure 1b.Furthermore the masonry comprises a raceway 2, located between said lower portions 61,64 of said first and second surfaces belonging to the masonry, for receiving at least one rail 41 on which rolls the lower rolling device 4 of the door of lock. This raceway 2 preferably comprises at least one other rail 41, and the rolling device 4 comprises at least one wheel 42, preferably two wheels 42 or four wheels 42 as shown in FIG. figure 1b .

Sur la figure 4a est également visible au moins un rail supérieur 51 situé en partie supérieure de la paroi 73 du logement de retrait. Par ailleurs est présent, de préférence, un deuxième rail supérieur 51 situé en partie supérieure de la paroi 71 du logement de retrait est visible sur la figure 4b.On the figure 4a is also visible at least one upper rail 51 located in the upper part of the wall 73 of the withdrawal housing. Furthermore, it is preferably a second upper rail 51 located in the upper part of the wall 71 of the withdrawal housing is visible on the figure 4b .

La figure 3 montre une coupe de la porte d'écluse roulante selon l'invention, selon la ligne de coupe III de la figure 1a. Sur la coupe sont illustrées la face supérieure 15, la première face principale 11 et la deuxième face principale 12, ainsi que la face inférieure 10.The figure 3 shows a section of the rolling lock gate according to the invention, along the section line III of the figure 1a . On the section are illustrated the upper face 15, the first main face 11 and the second main face 12, as well as the lower face 10.

La portion verticale avant 33 du premier dispositif d'étanchéité est située en vis-à-vis de la portion verticale avant 63 de la première portée de la maçonnerie d'écluse. La portion inférieure 31 du premier dispositif d'étanchéité est située en vis-à-vis de la portion inférieure 61 de la première portée de la maçonnerie d'écluse. La portion verticale avant 36 du deuxième dispositif d'étanchéité est située en vis-à-vis de la portion verticale avant 66 de la deuxième portée de la maçonnerie d'écluse. La portion inférieure 34 du deuxième dispositif d'étanchéité est située en vis-à-vis de la portion inférieure 64 de la deuxième portée de la maçonnerie d'écluse.The front vertical portion 33 of the first sealing device is located vis-à-vis the vertical front portion 63 of the first span of the lock masonry. The lower portion 31 of the first sealing device is located vis-à-vis the lower portion 61 of the first range of the lock masonry. The vertical front portion 36 of the second sealing device is located opposite the vertical front portion 66 of the second span of the lock masonry. The lower portion 34 of the second sealing device is located vis-à-vis the lower portion 64 of the second range of the lock masonry.

Le joint gonflable 6, visible (et partiellement arraché, pour montrer le premier dispositif d'étanchéité) sur la coupe de la figure 3, présente une épaisseur selon la direction X identique ou légèrement inférieure à l'épaisseur du premier dispositif d'étanchéité, lorsque ledit joint gonflable 6 est dégonflé.The inflatable seal 6, visible (and partially torn off, to show the first sealing device) on the section of the figure 3 , has a thickness in the X direction the same or slightly less than the thickness of the first sealing device, when said inflatable seal 6 is deflated.

Sur la figure 3, on constate qu'il existe un jeu selon la direction X entre les dispositifs d'étanchéité de la porte et les portées de maçonneries, en l'absence de sollicitations extérieures. En effet, la portion inférieure 31 du premier dispositif d'étanchéité est séparée de la portion inférieure 61 de la première portée de la maçonnerie d'écluse, située en regard, par un premier jeu fonctionnel et il en est de même pour la portion verticale 33 du premier dispositif d'étanchéité est séparée de la portion verticale 63 de la première portée de la maçonnerie par le même jeu fonctionnel.On the figure 3 it is found that there is a clearance in the X direction between the sealing devices of the door and the staves of masonry, in the absence of external solicitations. Indeed, the lower portion 31 of the first sealing device is separated from the lower portion 61 of the first scope of the lock masonry, located opposite, by a first functional game and it is the same for the vertical portion 33 of the first sealing device is separated from the vertical portion 63 of the first scope of the masonry by the same functional game.

De façon similaire, les portions horizontale et verticale 34,36 du deuxième dispositif d'étanchéité sont séparées des portions inférieure et verticale 64,66 de la deuxième portée de la maçonnerie d'écluse par un deuxième jeu fonctionnel, qui est sensiblement identique au premier jeu fonctionnel en l'absence d'efforts exercés sur la porte 1 selon la direction X.Similarly, the horizontal and vertical portions 34,36 of the second sealing device are separated from the lower and vertical portions 64,66 of the second span of the lock masonry by a second functional clearance, which is substantially identical to the first one. functional play in the absence of forces exerted on the door 1 according to the direction X.

La figure 5 est une vue schématique de dessus de la porte d'écluse roulante de la figure 1a, en situation dans la maçonnerie d'écluse. On y retrouve les éléments décrits précédemment. La porte d'écluse roulante 1 est représentée en position fermée et en position médiane selon la direction X, c'est-à-dire avec un jeu fonctionnel de chacun de cotés :

  • un premier jeu existe entre les portions horizontales et verticales 31,32,33 du premier dispositif d'étanchéité et les portions inférieures et verticales 61,62,63 de la première portée de la maçonnerie d'écluse,
  • un deuxième jeu existe entre les portions horizontales et verticales 34,35,36 du deuxième dispositif d'étanchéité et les portions inférieures et verticales 64,65,66 de la deuxième portée de la maçonnerie d'écluse.
The figure 5 is a schematic view from above of the rolling lock gate of the figure 1a , in situation in the lock masonry. It contains the elements described above. The rolling lock gate 1 is shown in the closed position and in the middle position in the X direction, that is to say with a functional play of each side:
  • a first clearance exists between the horizontal and vertical portions 31, 32, 33 of the first sealing device and the lower and vertical portions 61, 62, 63 of the first span of the lock masonry,
  • a second clearance exists between the horizontal and vertical portions 34,35,36 of the second sealing device and the lower and vertical portions 64,65,66 of the second span of the lock masonry.

En position fermée, la face d'extrémité avant 13 de la porte d'écluse roulante 1 se trouve en butée contre une butée avant 9 de la maçonnerie d'écluse.In the closed position, the front end face 13 of the rolling lock gate 1 is in abutment against a front stop 9 of the lock masonry.

Il est à noter que l'espacement entre les portions verticales arrière 62,65 respectivement des première et deuxième portées de la maçonnerie d'écluse est inférieure à l'écartement correspondant entre les portions verticales avant 63,66 respectivement des première et deuxième portées de la maçonnerie d'écluse, ceci pour permettre un retrait complet de la porte 1 dans le logement de retrait comme ceci est représenté sur la figures 2a.It should be noted that the spacing between the rear vertical portions 62,65 respectively of the first and second span of the lock masonry is less than the corresponding gap between the vertical portions before 63,66 respectively of the first and second lands of the lock masonry, to allow a complete removal of the door 1 in the housing of withdrawal as this is represented on the Figures 2a .

Par ailleurs, la figure 5 met en évidence le dispositif de roulement supérieur 5, muni de roues 52, aptes à rouler sur les rails 51. En outre l'extrémité arrière des rails inférieurs 41 du chemin de roulement 2 est visible.Moreover, the figure 5 highlights the upper rolling device 5, provided with wheels 52, able to roll on the rails 51. In addition the rear end of the lower rails 41 of the raceway 2 is visible.

La figure 6 est une vue schématique en coupe, parallèle au plan YZ, selon la ligne VI de la figure 5, où l'on voit que le deuxième dispositif d'étanchéité 34,35,36, se présente comme sous forme de 'U' ouvert le haut et de même forme que le 'U' formé par la deuxième portée de maçonnerie 64,65,66, de manière à pouvoir se plaquer l'un contre l'autre de manière continue sur toute la longueur de cette forme en 'U', procurant ainsi l'étanchéité recherchée.The figure 6 is a schematic sectional view, parallel to the YZ plane, along the line VI of the figure 5 , where it can be seen that the second sealing device 34,35,36, is in the form of a 'U' open top and of the same shape as the 'U' formed by the second masonry surface 64,65 , 66, so as to be able to press against each other continuously over the entire length of this U-shape, thereby providing the desired seal.

Sur la figure 6, la coupe met aussi en évidence une partie 120 du bord de la deuxième face principale, visible du fait que la portion verticale arrière 35 est en saillie par rapport aux autres portions du deuxième dispositif d'étanchéité, et est quelque peu décalée vers les X négatifs.On the figure 6 , the section also shows a portion 120 of the edge of the second main face, visible because the rear vertical portion 35 is projecting relative to the other portions of the second sealing device, and is somewhat offset to the X negative.

Sur l'extrémité avant de la maçonnerie se trouve la butée 9 de fin de course pour le déplacement de la porte. Le rail supérieur 51 se trouve quant à lui en partie supérieure de la paroi 73 du logement de retrait de la porte.On the front end of the masonry is the end stop 9 for the movement of the door. The upper rail 51 is located in the upper part of the wall 73 of the door recess housing.

La figure 7 est une vue partielle de dessus de l'extrémité avant de la porte d'écluse roulante lorsque celle-ci est plaquée par la pression (cette pression peut être une pression de liquide P ou une pression générée par des moyens mécaniques ou hydrauliques) en direction de la première portée de la maçonnerie (vers les X positifs). Dans cette configuration, la porte est décalée de sa position neutre dans la direction X et sa première face principale 11 bute sur la première portée de la maçonnerie 61,62,63. Ceci a pour conséquence d'isoler de façon étanche le premier espace 81 par rapport à l'espace interne 16 de la porte d'écluse, au chemin de roulement 2 et au deuxième espace 82.The figure 7 is a partial top view of the front end of the rolling lock gate when the latter is pressed by the pressure (this pressure may be a liquid pressure P or a pressure generated by mechanical or hydraulic means) in the direction of the first range of masonry (towards positive X's). In this configuration, the door is shifted from its neutral position in the X direction and its first main face 11 abuts on the first range of the masonry 61,62,63. This has the effect of sealingly isolating the first space 81 relative to the internal space 16 of the lock gate, the raceway 2 and the second space 82.

En effet, la portion horizontale 31 avant du premier dispositif d'étanchéité est plaquée contre la portion inférieure 61 de la première portée de la maçonnerie d'écluse. De même, les portions verticales avant et arrière 33, 32 du premier dispositif d'étanchéité sont respectivement plaquées contre les portions verticales avant et arrière 63,62 de la première portée de la maçonnerie d'écluse. Il est à noter que la première face principale 11 présente une surface continue à l'intérieur de la surface délimitée par le 'U' formé par le premier dispositif d'étanchéité, donc l'eau ne peut pas passer à travers la première face principale 11.Indeed, the horizontal portion 31 before the first sealing device is pressed against the lower portion 61 of the first span of the lock masonry. Similarly, the front and rear vertical portions 33, 32 of the first sealing device are respectively pressed against the front and rear vertical portions 63,62 of the first span of the lock masonry. It should be noted that the first main face 11 has a continuous surface inside the surface delimited by the 'U' formed by the first sealing device, so the water can not pass through the first main face 11.

Du coté opposé, à savoir du côté de la seconde face principale 12, il existe un jeu fonctionnel 26 plus important, le deuxième dispositif d'étanchéité 34,35,36 étant éloigné de la deuxième portée de la maçonnerie 64,65,66.On the opposite side, namely on the side of the second main face 12, there is a greater functional clearance 26, the second sealing device 34,35,36 being away from the second range of the masonry 64,65,66.

La figure 8 est une coupe en élévation de la porte d'écluse roulante selon l'invention, dans la configuration représentée sur la figue 7 décrite précédemment. La porte étant plaquée sur sa première face principale 11 par la pression P régnant dans le deuxième espace 82, supérieure à la pression prévalant dans le premier espace 81, le premier dispositif d'étanchéité 31,32,33 est pressé contre la première portée 61,62,63 de la maçonnerie d'écluse, procurant ainsi une séparation étanche entre l'espace 81 et l'espace interne 16 de la porte 1.The figure 8 is a sectional elevation of the rolling lock gate according to the invention, in the configuration shown in Fig 7 previously described. The door being pressed on its first main face 11 by the pressure P prevailing in the second space 82, greater than the pressure prevailing in the first space 81, the first sealing device 31,32,33 is pressed against the first bearing 61 , 62.63 of the lock masonry, thus providing a tight separation between the space 81 and the internal space 16 of the door 1.

Du coté de la seconde face principale 12, le deuxième dispositif d'étanchéité 34,35,36 étant éloigné de la deuxième portée de la maçonnerie 64,65,66, et le jeu fonctionnel 26 laisse passer l'eau en provenance du deuxième espace 82, cette eau remplissant l'espace intérieur 16 de la porte, y compris la cavité d'accès 3 en partie inférieure, et aussi le chemin de roulement 2. Le niveau d'eau à l'intérieur de la porte est au même niveau que l'eau dans le deuxième espace 82.On the side of the second main face 12, the second sealing device 34,35,36 being away from the second range of the masonry 64,65,66, and the functional clearance 26 passes water from the second space 82, this water filling the internal space 16 of the door, including the access cavity 3 in the lower part, and also the raceway 2. The water level inside the door is at the same level as the water in the second space 82.

La figure 9 est une vue analogue à la figure 5, la porte étant plaquée sur sa première face principale 11 par la pression, avec un dispositif d'étanchéité auxiliaire 37,38,39 en position. Ce dispositif d'étanchéité auxiliaire comprend une partie inférieure 37, une partie verticale arrière 38, et une partie verticale avant 39 (qui sont illustrés également sur la figure 10). La partie inférieure 37 porte sur la portion horizontale 67 de la portée auxiliaire de la maçonnerie d'écluse, la partie verticale arrière 38 porte sur la portion verticale arrière 68 de la portée auxiliaire de la maçonnerie d'écluse, et la partie verticale avant 39 porte sur la portion verticale avant 69 de la portée auxiliaire de la maçonnerie d'écluse. Ces éléments d'étanchéité auxiliaires 37,38,39 coopèrent avec les portions 67,68,69 de la portée auxiliaire de la maçonnerie pour isoler de façon étanche le chemin de roulement 2 et l'espace intérieur 16 de la porte 1 par rapport au deuxième espace 82.The figure 9 is a view similar to the figure 5 , the door being pressed on its first main face 11 by pressure, with an auxiliary sealing device 37,38,39 in position. This auxiliary sealing device comprises a lower part 37, a rear vertical part 38, and a front vertical part 39 (which are also illustrated on FIG. figure 10 ). The lower portion 37 bears on the horizontal portion 67 of the auxiliary span of the lock masonry, the rear vertical portion 38 on the rear vertical portion 68 of the auxiliary span of the lock masonry, and the vertical front portion 39 door to the front vertical portion 69 of the auxiliary span of the lock masonry. These auxiliary sealing elements 37, 38, 39 cooperate with the portions 67, 68, 69 of the auxiliary surface of the masonry to seal the raceway 2 and the interior space 16 of the door 1 with respect to the second space 82.

Ainsi le logement de retrait 7, l'espace interne 16 de la porte 1 et la cavité d'accès 3 sont isolés de manière étanche des deux étendues d'eau 81,82. On peut alors procéder à l'assèchement de cette zone. Pour ce faire, un dispositif de pompage 19 (non détaillé car connu dans l'état de la technique) est utilisé : on prélève l'eau se situant dans le logement de retrait 7 jusqu'à assèchement de celui-ci, ainsi que de la cavité d'accès 3 qui est en communication fluide avec ledit logement de retrait 7.Thus the recess housing 7, the internal space 16 of the door 1 and the access cavity 3 are sealingly insulated from the two bodies of water 81,82. This area can then be dewatered. To do this, a pumping device 19 (not detailed because known in the state of the art) is used: the water is taken from the withdrawal housing 7 until dry, as well as the access cavity 3 which is in fluid communication with said withdrawal housing 7.

Après que la cavité d'accès 3 a été vidée et asséchée, il est possible pour un humain de descendre dans ladite cavité d'accès 3, empruntant un passage 17 prévu à cet effet, situé dans l'espace interne 16 de la porte 1, et qui s'étend depuis la face supérieure 15 jusqu'à la cavité d'accès 3, et comportant par exemple un ou plusieurs escaliers 17. La cavité d'accès 3 étant ouverte vers le bas, le ou les intervenants humains peuvent inspecter le chemin de roulement 2, le ou les rails 41, qui le reste du temps sont inaccessibles car immergés.After the access cavity 3 has been emptied and dried, it is possible for a human to descend into said access cavity 3, taking a passage 17 provided for this purpose, located in the internal space 16 of the door 1, and which extends from the upper face 15 until to the access cavity 3, and comprising for example one or more stairs 17. The access cavity 3 being open downwards, the human intervener or workers can inspect the raceway 2, the or rails 41, which the rest of the time are inaccessible because immersed.

Comme illustré sur les figures 8, 9 et 10, l'élément inférieur 37 du dispositif d'étanchéité auxiliaire peut être montée mobile sur la deuxième face principale 12 de la porte roulante, par exemple pivotante autour d'un axe de rotation horizontal 370. Sur la figure 8, l'élément inférieur 37 est en position de retrait, relevé contre la deuxième face principale 12, parallèlement à celle-ci. Sur les figures 9 et 10, l'élément inférieur 37 est en position active, c'est-à-dire porte sur la portée auxiliaire horizontale 67 de la maçonnerie.As illustrated on figures 8 , 9 and 10 , the lower element 37 of the auxiliary sealing device can be mounted movably on the second main face 12 of the rolling door, for example pivoting about a horizontal axis of rotation 370. On the figure 8 , the lower member 37 is in the retracted position, raised against the second main face 12, parallel to it. On the figures 9 and 10 , the lower member 37 is in the active position, that is to say on the horizontal auxiliary bearing surface 67 of the masonry.

Grâce à cette disposition, l'élément inférieur 37 peut être facilement manoeuvré entre la position de retrait et la position active, et inversement, et on évite une opération de manutention difficile pour amener et descendre au fond de l'écluse ledit élément inférieur 37.Thanks to this arrangement, the lower element 37 can be easily operated between the retracted position and the active position, and vice versa, and a difficult handling operation is avoided to bring the lower element 37 down to the bottom of the lock.

La figure 11 est une vue partielle de dessus de l'extrémité avant de la porte d'écluse roulante 1, dans une configuration différente des précédentes, la porte étant plaquée cette fois sur sa deuxième face principale 12 par la pression P qui règne dans le premier espace 81, supérieure à la pression qui règne dans l'espace 82.The figure 11 is a partial view from above of the front end of the rolling lock gate 1, in a configuration different from the previous ones, the door being pressed this time on its second main face 12 by the pressure P which reigns in the first space 81 , greater than the pressure that reigns in space 82.

Dans cette configuration, la porte est décalée de sa position neutre dans la direction des X négatifs et sa deuxième face principale 12 bute sur la deuxième portée de la maçonnerie 64,65,66. Ceci a pour conséquence d'isoler de façon étanche le deuxième espace 82 par rapport à l'espace interne 16 de la porte d'écluse, au chemin de roulement 2 et au premier espace 81.In this configuration, the door is shifted from its neutral position in the direction of the negative X and its second main face 12 abuts on the second range of the masonry 64,65,66. This has the effect of sealingly isolating the second space 82 relative to the internal space 16 of the lock gate, the raceway 2 and at the first space 81.

En effet, la portion horizontale 34 du deuxième dispositif d'étanchéité est plaquée contre la portion inférieure 64 de la deuxième portée de la maçonnerie d'écluse. De même, les portions verticales avant et arrière 36, 35 du deuxième dispositif d'étanchéité sont respectivement plaquées contre les portions verticales avant et arrière 66,65 de la deuxième portée de la maçonnerie d'écluse. Il est à noter que, comme la première face principale 11, la deuxième face principale 12 présente une surface continue à l'intérieur de la surface délimitée par le 'U' formé par le deuxième dispositif d'étanchéité, donc l'eau ne peut pas passer à travers la deuxième face principale 12.Indeed, the horizontal portion 34 of the second sealing device is pressed against the lower portion 64 of the second range of the lock masonry. Likewise, the front and rear vertical portions 36, 35 of the second sealing device are respectively pressed against the front and rear vertical portions 66, 65 of the second span of the lock masonry. It should be noted that, like the first main face 11, the second main face 12 has a continuous surface inside the surface delimited by the 'U' formed by the second sealing device, so the water can not not pass through the second main face 12.

Comme cela a été indiqué au début de la description, le niveau de liquide dans l'espace 82 peut être piloté par des moyens hydrauliques. En particulier, le niveau peut être abaissé jusqu'à ce que ce deuxième espace 82 soit complètement vidé. En effet, si l'on veut construire ou réparer un navire à sec, on procède à l'assèchement du deuxième espace 82 (comme cela est illustré sur la figure 2c.As indicated at the beginning of the description, the liquid level in the space 82 can be controlled by hydraulic means. In particular, the level can be lowered until this second space 82 is completely emptied. Indeed, if we want to build or repair a dry ship, we proceed to the drying of the second space 82 (as illustrated on the Figure 2c .

Du coté opposé, à savoir du côté du premier espace 81 et de la première face principale 11, il existe un jeu fonctionnel 23 important, le premier dispositif d'étanchéité 31,32,33 étant éloigné de la première portée de la maçonnerie 61,62,63, l'eau du premier espace 81 peut donc pénétrer par ce jeu dans l'espace intérieur 16 de la porte.On the opposite side, namely on the side of the first space 81 and the first main face 11, there is a large functional clearance 23, the first sealing device 31, 32, 33 being remote from the first span of the masonry 61, 62,63, the water of the first space 81 can thus enter through this clearance in the interior space 16 of the door.

La figure 12 est une coupe en élévation de la porte d'écluse roulante, la porte étant plaquée sur sa deuxième face principale 12 par la pression du premier espace 81, et le deuxième espace ayant été asséché comme cela a été décrit à propos de la figure 11. Dans ces conditions, quelque soit la hauteur du niveau dans le premier espace 81, il est supérieur à celui prévalant dans le deuxième espace 82 (qui lui est au sec) : ainsi la porte d'écluse reste plaquée contre la deuxième portée de maçonnerie 64,65,66. Un chantier de construction de navire peut durer plusieurs mois, et donc la porte d'écluse restera immobile dans la position de la figure 12 tout le temps que durera la construction du navire.The figure 12 is a sectional elevation of the rolling lock gate, the door being pressed against its second main face 12 by the pressure of the first space 81, and the second space having been dried as has been described in connection with the figure 11 . Under these conditions, whatever the height of the level in the first space 81, it is greater than that prevailing in the second space 82 (which is dry): thus the lock gate remains pressed against the second masonry 64,65,66. A ship building site can last several months, and thus the lock gate will remain stationary in the position of the figure 12 all the time that will last the construction of the ship.

La figure 12 met aussi en évidence une cavité inférieure 8, délimitée vers le bas par le chemin de roulement 2, vers le haut par la face inférieure 10 de la porte 1, et sur les cotés par les portions inférieures 61,64 des première et deuxième portées de la maçonnerie d'écluse. C'est généralement dans cette cavité que s'accumulent les détritus et/ou la vase, qui se déposent ensuite sur le chemin de roulement 2.The figure 12 also shows a lower cavity 8, bounded downwards by the race 2, upwards by the lower face 10 of the door 1, and on the sides by the lower portions 61,64 of the first and second spans of FIG. lock masonry. It is generally in this cavity that detritus and / or mud accumulate, which are then deposited on the raceway 2.

Dans ces conditions, si aucune précaution n'est prise, compte-tenu du jeu 23 qui laisse rentrer et sortir l'eau du côté de la première face principale 11 et du premier espace 81 au gré des marées, de la vase et/ou des détritus s'accumulent petit à petit au niveau du chemin de roulement 2. Ceci devient problématique le jour où l'on veut à nouveau manoeuvrer la porte d'écluse 1 pour la déplacer vers sa position ouverte : la vase et les détritus présents sur le chemin de roulement 2 empêche la roue 42 de rouler correctement sur le rail 41.Under these conditions, if no precaution is taken, taking into account the game 23 which lets in and out the water side of the first main face 11 and the first space 81 at the option of the tides, the mud and / or litter accumulates little by little at the level of the raceway 2. This becomes problematic on the day when we want to maneuver again the lock gate 1 to move it towards its open position: the mud and the detritus present on the raceway 2 prevents the wheel 42 from rolling correctly on the rail 41.

Pour pallier cet inconvénient, l'invention propose l'utilisation du joint d'étanchéité gonflable 6, qui peut être gonflé ou dégonflé, et dont le fonctionnement va être décrit ci-après.To overcome this drawback, the invention proposes the use of the inflatable seal 6, which can be inflated or deflated, and whose operation will be described below.

La figure 13 est une vue analogue aux figures 5 et 9, la porte étant plaquée cette fois sur sa deuxième face principale 12 par la pression. Dans toutes les figures précédentes 1 à 12, le joint d'étanchéité gonflable 6 est à l'état de repos, c'est-à-dire non gonflé ; en revanche dans le cas illustré sur la figure 13 (et aussi sur les figures 14 et 16b) le joint d'étanchéité gonflable 6 est en position gonflé.The figure 13 is a view similar to figures 5 and 9 , the door being pressed this time on its second main face 12 by pressure. In all the previous figures 1 to 12, the inflatable seal 6 is in the state of rest, that is to say not inflated; on the other hand in the case illustrated on the figure 13 (and also on figures 14 and 16b ) the inflatable seal 6 is in the inflated position.

Dans cette position, le joint d'étanchéité gonflable 6 s'étend en direction opposé à la première face principale 11, et sur toute la longueur du joint d'étanchéité gonflable 6, il vient porter sur la première portée de maçonnerie 61,62,63.In this position, the inflatable seal 6 extends in a direction opposite to the first main face 11, and over the entire length of the inflatable seal 6, it comes to bear on the first masonry bearing 61,62, 63.

Ainsi il obture le jeu 23 entre la première face principale 11 et la première portée de maçonnerie 61,62,63, si bien que l'espace interne 16 de la porte, la cavité d'accès 3 et le chemin de roulement 2 ne sont plus en communication directe avec le premier espace 81. De même, la cavité inférieure 8 ainsi que le logement de retrait 7 sont isolés du premier espace et on évite ainsi que des détritus ou de la vase viennent se déposer sur le chemin de roulement 2.Thus it closes the clearance 23 between the first main face 11 and the first masonry surface 61, 62, 63, so that the internal space 16 of the door, the access cavity 3 and the raceway 2 are more in direct communication with the first space 81. Similarly, the lower cavity 8 and the recess housing 7 are isolated from the first space and it is thus possible that detritus or mud are deposited on the raceway 2.

La figure 14 est une vue analogue à la figure 12, dans laquelle le joint gonflable est gonflé, configuration identique à celle qui vient d'être décrite pour la figure 13.The figure 14 is a view similar to the figure 12 , in which the inflatable seal is inflated, identical configuration to that just described for the figure 13 .

Il est à noter que l'espace interne 16 de la porte 1, y compris la cavité d'accès 3 située dans la partie inférieure, restent remplis d'eau, mais sans communication avec le premier espace 81.It should be noted that the internal space 16 of the door 1, including the access cavity 3 located in the lower part, remain filled with water, but without communication with the first space 81.

La figure 15 est une est une vue schématique en coupe, parallèle au plan YZ, selon la ligne XV de la figure 13, où l'on voit que le joint d'étanchéité gonflable 6 s'étend continument le long de la première portée de maçonnerie en parcourant une forme de 'U', et comprenant une partie inférieure 6a, une partie verticale avant 6b et une partie verticale arrière 6c, de manière à pouvoir se plaquer contre le 'U' formé par la première portée de maçonnerie 61,32,63.The figure 15 is a schematic sectional view, parallel to the YZ plane, along line XV of the figure 13 , where it can be seen that the inflatable seal 6 extends continuously along the first masonry span by traversing a 'U' shape, and comprising a lower portion 6a, a front vertical portion 6b and a portion vertical rear 6c, so as to be pressed against the 'U' formed by the first masonry 61,32,63 range.

Le joint d'étanchéité gonflable 6 est réalisé de manière monopièce, la partie inférieure 6a étant reliée en continuité avec respectivement la partie verticale avant 6b et avec la partie verticale arrière 6c.The inflatable seal 6 is made in one piece, the lower part 6a being connected in continuity with the front vertical portion 6b respectively and with the rear vertical portion 6c.

Le premier dispositif d'étanchéité 31,32,33, se présente aussi sous forme de 'U' ouvert le haut et de même forme que le 'U' formé par la première portée de maçonnerie 61,32,63 de manière à pouvoir se plaquer l'un contre l'autre de manière continue sur toute la longueur de cette forme en 'U', procurant ainsi l'étanchéité recherchée.The first sealing device 31, 32, 33 is also in the form of a 'U' open top and of the same shape as the 'U' formed by the first masonry span 61, 32, 63 so as to be able to press one against the other in a continuous manner on any the length of this shape in 'U', thus providing the desired seal.

Sur la figure 15, la coupe met aussi en évidence une partie 110 du bord de la première face principale, visible du fait que la portion verticale arrière 32 est en saillie par rapport aux autres portions du premier dispositif d'étanchéité, et est quelque peu décalée vers les X positifs.On the figure 15 , the section also shows a portion 110 of the edge of the first main face, visible because the rear vertical portion 32 is projecting relative to the other portions of the first sealing device, and is somewhat offset to the X positive.

Les figures 16a et 16b sont des vues de détail montrant une section du joint d'étanchéité gonflable 6, respectivement à l'état dégonflé (figure 16a), et gonflé (figure 16b).The Figures 16a and 16b are detailed views showing a section of the inflatable seal 6, respectively in the deflated state ( figure 16a ), and inflated ( figure 16b ).

Le profil du joint d'étanchéité gonflable 6 comprend une base 94 parallèle à la première face principale 11, des première et deuxième joues latérales 92,93, s'étendant perpendiculairement à la dite base 94, et une partie de membrane souple 90,91 qui se déplace entre une position de retrait 90 si le joint d'étanchéité gonflable 6 est dégonflé et une position en saillie 91 si le joint d'étanchéité gonflable 6 est gonflé.The profile of the inflatable seal 6 comprises a base 94 parallel to the first main face 11, first and second lateral flanges 92, 93, extending perpendicularly to said base 94, and a flexible membrane portion 90, 91 which moves between a retracted position 90 if the inflatable seal 6 is deflated and a protruding position 91 if the inflatable seal 6 is inflated.

Dans l'état dégonflé, la partie de membrane souple ne dépasse pas de l'épaisseur défini par la portion inférieure du premier dispositif d'étanchéité 31, alors que dans l'état gonflé, la partie de membrane souple fait saillie et vient porter contre la partie inférieur 61 de la première portée de maçonnerie, annulant ainsi le jeu 23 créé du fait que la porte est plaquée contre la deuxième portée de maçonnerie.In the deflated state, the flexible membrane portion does not exceed the thickness defined by the lower portion of the first sealing device 31, whereas in the inflated state, the flexible membrane portion protrudes and bears against the lower portion 61 of the first masonry span, thus canceling the clearance 23 created by the fact that the door is pressed against the second masonry span.

Le profil en section du joint d'étanchéité gonflable 6 qui vient d'être décrit s'étend continument sur la totalité de la longueur du dit joint d'étanchéité gonflable 6, définissant ainsi un espace intérieur 95 qui s'étend tout le long du 'U' formé par le joint d'étanchéité gonflable 6. Par conséquent, il suffit de connecter cet espace 95 à un dispositif de gonflage (non représenté) par exemple au niveau de l'extrémité supérieure de la portion verticale arrière 6c du joint d'étanchéité gonflable 6, pour qu'il soit possible de gonfler simultanément l'ensemble du joint d'étanchéité gonflable 6, ou inversement de la dégonfler simultanément.The sectional profile of the inflatable seal 6 which has just been described extends continuously over the entire length of said inflatable seal 6, thus defining an interior space 95 which extends all along the 'U' formed by the seal 6. Therefore, it is sufficient to connect this space 95 to an inflation device (not shown) for example at the upper end of the rear vertical portion 6c of the inflatable seal 6, so that it is it is possible to simultaneously inflate the assembly of the inflatable seal 6, or conversely to deflate it simultaneously.

Par ailleurs, selon l'invention, le joint d'étanchéité gonflable 6 est équipé d'un capteur de pression 96 qui permet de contrôler la pression régnant dans l'espace intérieur 95 du joint d'étanchéité gonflable 6, de manière en particulier à détecter une fuite potentielle.Furthermore, according to the invention, the inflatable seal 6 is equipped with a pressure sensor 96 which makes it possible to control the pressure prevailing in the inner space 95 of the inflatable seal 6, in particular so as to detect a potential leak.

Par ailleurs, selon l'invention, un deuxième joint d'étanchéité gonflable, analogue au premier, peut être monté sur la deuxième face principale 12 de la porte, avec une géométrie symétrique par rapport au plan YZ. Ce deuxième joint d'étanchéité gonflable, monté sur la deuxième face principale 12, peut être une solution complémentaire du dispositif d'étanchéité auxiliaire 37,38,39 ou même remplacer ce même dispositif d'étanchéité auxiliaire 37,38,39 pour éviter les manoeuvres de mise en place de ce dernier.Furthermore, according to the invention, a second inflatable seal, similar to the first, can be mounted on the second main face 12 of the door, with a geometry symmetrical with respect to the YZ plane. This second inflatable seal, mounted on the second main face 12, may be a complementary solution of the auxiliary sealing device 37,38,39 or even replace this same auxiliary sealing device 37,38,39 to avoid maneuvers to set up the latter.
